Darwin used systematic notes abstracting the points of interest in numerous scientific books and journals as a way of annotating literature that, in large part, he did not own. These abstracts are located in DAR 71-75. In addition, Darwin’s many loose reading notes with bibliographic information are found intermingled with his other notes all over the archive.
